couple of questions before i go and waste a feat on exotic weapons. i am running a toranite paladin who hopes to be an undead slayer. i believe most if not all undead are immune to critical hits. is this weapon worth it for a paladin and is it even useable by a toranite -- i.e. do the weapon specializations and focus on longsword count with this weapon? looking for some advice. thanks, redhawk
